Speaking of poop, Darcy pooped a handful a few hours after he ate a humongous chunk of the sinking shrimp pellet. Usually he just throws up if it's too large, but he was able to keep it down. He then proceeded to poop one, two, three doo-doos :)

I suspect the orange blob in the picture above is half-digested food that Darcy threw up. It is huge. Usually his poop looks like the skinny end of that blob. I don't think it is fishly possible to poop something that large.
